SMOKING PIPE.

Application filed. October 27, 1921. Serial No. 510,942.

To aZZ whom it may concern:

Be it known that we, Jaoon D. BURGER, a citizen of the United States, and a resident of New York, county of New York, State of blew York, and Rononrrr Hrnsorr, a citizen of the United States, and a resident of Nest New York, county of Hudson, State of New Jersey, have invented a certain'new and useful Improvement in Smoking Pipes, of which the following is a specification.

This invention relates to smoking pipes, and more particularly to those provided with a removable bowl. In the use of pipes of this character the connection between the bowl and the base of the pipe very often becomes broken or impaired to the extent that the bowl will not stay in place. Sometimes the threads of the screw threaded connection vet-ween the bowl and the base are attacked by certain chemical elements, so that the threads are eaten away, and sometimes they are broken. This is very often the case where the threaded connection is formed from the same materials from which the bowl itself is made, being an integral portion thereof.

Furthermore, in smoking pipes in which a well is provided below the bowl to collect liquid. the formation and construction are such, in certain pipes heretofore manufac tured, that the accumulation in the well was liable to be drawn into the passage in the stem or mouth piece, and into the mouth of the smoker. I Generally stated, therefore, the object of the invention. is to provide an improved smoking pipe having a removable bowl provided with a practically non-breakable screw connection at the base of the pipe, and it is also an object to provide an improved construction whereby the well below the bowl is so connected with the stem or mouth piece that any accumulation in the well is not liable to be sucked into the stem and into the mouth of the smoker.

It is also an object to provide certain fea tures and details of construction tending to increase the general efficiency and desirability of a smoking pipe of this particular character.

To these and other useful ends the invention consists in matters hereinafter set forth and claimed and shown in the accompanying drawings, in which:

Figure l is a side elevation of a smoiring pipe embodying the principles of the invention, sho 'ing the bowl and a portion of the base in vertical longitudinal section.

Figure 2 is a side elevation of the nonbreakable and lire-proof screw connection between the bowl and the base.-

Figure 3 is a horizontal section on line in Figure 2.

Figure a is a view similar to Figure 1, but showing a different form of the invention, and showing the bit or mouth piece broken away for convenience in illustration.

Figure is a bottom view of the screw connection shown in Figure at.

As thus illustrated, the invention comprises a bowl 1 of briar or other suitable material, a base 2 of amber, redmanol or other suitable material, and a mouth piece or hit 3 of any suitable material, but preferably of the same material as said base. The screw 4 is preferably of asbestos or bakelite or condensite, and is screwed into the bottom of said bowl. Said screw t has a vertical duct 5 and a lateral duct 6, and is adapted to be screwed into the threaded socket 7 formed in said base. A well 8 is formed in the base below said screw, so that liquid from the bowl of the pipe may drop through the duct 5 and accumulate in said well. The base 2 has a longitudinal passage 9 which stops short of said well, and an. inclined duct 10 connects this passage with the lateral duct 6 previously mentioned, so that smoke is drawn down through the duct 5, then through the duct 10 into the passage 9 which communicates with the usualpassage in the mouth piece or bit 3 of the pipe. In this way liquid that accumulates in the well 8 is prevented from flowing into the passage 9, but at the same time a free passage is provided for thesmoke. Moreover, it will be seen, the hard screw 4;, which is both fireproof and non-breakable, provides a practically non-breakable screw connection between the bowl and the base. When a removable bowl is formed with an integral portion for said screw, breakage is liable to occur, inasmuch as the threads of the screw are of the same material as the bowl and the latter is usually of briar or meerschaum or some other material which is satisfactory for the bowl, but which is not adapted for the formation of satisfactory screw threads;

and, therefore, by using a separately formed screw, as shown, which is permanently cemented or otherwise secured in the bottom of the bowl, a non-breakable connection is provided between the bowl and the base, as the threads for the screw connection are formed of hard and tough material. In Figure 1 the screw 4 forms the bottom of the cavity in the bowl, but in Figure 4 the bottom 11 of the bowl itself covers the top of said screw 4, so that the latter is not in con tact with the contents of the bowl, also, as shown in Figures 4 and 5 the bottom oi the screw 4 is provided with a cavity 12 which increases the height of the well 8 in the base, and with this construction the liquid accumulation in the well is not liable to be drawn upward and then into the stem or mouth piece of the pipe. In either case, however,

. the screw 4 is permanently fixed in the bottom of the bowl, and forms a part of the bowl, so that the latter can be rotated torcibly to screw the threaded connection into the base or to unscrew it therefrom. Any suitable materials can be employed, but it will be seen that the foregoing construction permits the use of materials for the bowl which are best suited for the purpose, and other materials which are best suited, or which are highly desirable for the base and mouth piece, while, at the same time, the screw threaded connection is formed by materials which are best suited for such purpose. It will be seen that the duct 6 is prel erably flared 01' widened at its outer end as shown in Figure 3, so that it will be easier to cause this duct to register with the duct 10 when the bowl is screwed in place. Oi course, the screw threaded connection is so proportioned or formed that when the bowl is screwed up tight the duct 6 will register with the duct 10, in the manner shown in the drawings, thus providing a free passage for the smoke from the bowl to the .stem or mouth piece of the pipe. The passage 9 can be easily formed in the base 2, and the duct 10 can be easily bored at the angle shown, so that the construction is not only intended to be more satisfactory in use, but is also of a character to permit the pipe to be manufactured by comparatively inexpensive methods.

lVhat we claim as our invention is:

1. In a smoking pipe, a bowl of suitable material, a screw of different material on the bottom of said bowl, a base having a socket formed to engage the screw to removably hold said bowl in position, and a stump integral with said base, the bottom of the bowl engaging the base, forming a joint between them below the well of the bowl.

2. A smoking pipe as specified in claim 1, said screw having a cavity in its top to form the bottom of the bowl cavity and being fireproof and harder than the bowl to form a non-breakable connection between the bowl and the base.

3. A smoking pipe as specified in claim 1, said screw having a lateral smoke duct in the side thereof and a vertical duct at its center, with a well in said base, a longitudinal passage in the base, and a duct in the base to connect said passage with said lateral duct, substantially as shown and described.

4. A smoking pipe comprising a base having a well therein, a removable bowl engaging said base and having a vertical duct extending down from its own well to said well in the base, a passage in said base, and a duct extending from said passage and communicating laterally with said vertical duct.

5. A smoking pipe as specified in claim 4, said bowl having a screw with said vertical duct and its lateral communication therein, forming a connection with said base.

6. A structure as specified in claim 4, said bowl being removable, said longitudinal passage being straight and stopping short of said well, and said communicating duct being formed partly in the base and partly in the removable bowl.

'7. A structure as specified in claim 1, said screw being permanently inserted in a threaded socket formed in the flat bottom of the bowl, whereby the screw extends above and below said fiat bottom, and so that the screw is a fixed portion of the bowl.

8. A. smoking pipe comprising a bowl of suitable material, a base of suitable material, a one-piece screw member of different material, said member being threaded continuously from one end to the other and screwed into the base and also into the bottom of said bowl, forming a concealed and separable connection of a very strong and solid character between the bowl and the base, and a mouthpiece and stump rigid with said base, said member having a single and central bore forming a duct through which smoke is drawn from the bowl to the base, and finally to the mouthpiece.

9. A structure as specified in claim 8, said member forming the bottom of the cavity of said bowl.
